In case you have trouble with dynamic loading of shared libraries,
you will find that a static gdbserver comes in handy.
+ However, it has been noticed at least on x86 that enabling this
+ option produces an invalid gdbserver binary. It is linked with
+ "-static -Wl,--dynamic-list=..." which
+ # (a) requests invalid program interpreter
+ # (b) crashes glibc/uClibc-ng and does not work with musl
+ # See https://sourceware.org/ml/libc-alpha/2017-03/msg00267.html
+
+ It is possible it would work with other architectures, hence it is
+ not completely removed. Use with care and report to the mailing list
+ if the resulting gdbserver works.
+
+ For further details, see:
